You must level up before venturing forth

I don't think this is a spoiler. More like a warning.

 

When you finish the main quest, the game is over. Also, it's hard. Do your leveling up before you go past the point of no return. I guess I was thinking that I would be able to keep playing past the end. Not sure why I thought that.

 

I did it at level 10 but had to drop down to easy and still almost couldn't do it. There are probably trick builds that can do it at low level, but that wasn't me.

I was at level 12, and I found it to be a fairly easy fight (playing on Normal). The Master Beneath Caed Nua feels like the real "final boss" of the game, to me.
